jquery text changes trigger events such as focus events, event loss, etc., here is an example, interested friends can refer to the followingJuery Event: The code is as follows: $ ("#id"). focus (function () {}); Defocus Event: The code is as follows: $ ("#id"). blur (function () {}); But text change events cannot be written like this: The code is as follows: $
The off () function removes the event handler for one or more events bound by an element.
The off () function is primarily used to disassociate the event handler functions that are bound by the on () function.
This function belongs to the jquery object (instance).
Grammar
JQuery 1.7 adds this function. It is mainly used in the following two types of usage:
Usage One:

We often talk about onBlur events, onfocus events (js), and onbluronfocus events.
The onFocus event is an event that occurs when the cursor falls in the text box.
An onBlur event is an event that occurs when the cursor loses focus.
You can compile the following example:
1. html
Another example is as follows:

This article introduces the use of traditional events to simulate modern events, very simple and practical, the need for small partners can refer to.
As we all know, the modern event binding (attachevent) in IE has many problems compared with the standard of the AddEventListener.
For example: memory leaks, recurring events and triggers are flashback execution,
This blog is a presentation that describes using COOCS2DX Lua with touch events. For Main.lua files, look in the previous articles in the same series.
The underlying content will no longer be explained, and this article will focus on the content. Use the steps to create the listener you want (touch listener, Keyboard listener). Listener settings are swallowed. The listener sets the type of event to listen on (CC. Handler.event_touch_began), as well as

The onfocus event is the event that occurs when the cursor falls in a text box.
The onblur event is the event that occurs when the cursor loses focus.

As we all know, the modern event binding (attachevent) in IE has many problems compared with the standard of the AddEventListener.
For example: memory leaks, recurring events and triggers are flashback execution, and so on.
The following is a traditional event method to handle the binding of an encapsulated event:
Addevent.id = 1;

Implementation code
Copy Code code as follows:
function Stopevent (evt) {
var evt = evt | | window.event;
if (Evt.preventdefault) {
Evt.preventdefault ();
Evt.stoppropagation ();
} else {
Evt.returnvalue = false;
Evt.cancelbubble = true;
}
}
Prevent events from continuing to propagate only (do not cancel the default behavior)
